This adds a random provider which makes usage of random operations mockable, and may allow us in the future to swap out the Cryptographical CPU random generator with dedicated hardware random generators.
This moves a lot of machinery for commands into a context.Context with other struct values. This allows for PreRunE's to reliably load the configuration and avoids use of global vars.
This improves all random character generator command usages to be nearly identical and reuse a large block of code. It also improves several functions to give more options when randomly generating outputs.
This expands the functionality of the certificates and rsa commands and merges them into one command called cypto which can either use the cert or pair subcommands to generate certificates or key-pairs respectively. The rsa, ecdsa, and ed25519 subcommands exist for both the cert and pair commands. A new --ca-path argument for the cert subcommand allows Authelia to sign other certs with CA certs.
